With plain localhost, node >=17 can bind the Vite dev server to ::1
only; on this machine IPv4/IPv6 loopback mismatch made the browser,
wait-on, and the Electron window all see connection-refused while Vite
reported ready. Explicit 127.0.0.1 on all three ends fixes dev startup
(user-verified: electron:dev window now opens).
